Dainther is the slash ship between Dainsleif and Aether from the Genshin Impact fandom.

Canon[]

Depending of the chosen twin, Dainsleif will accompany the Traveler in all the Traveler's Quest Acts. If the player chooses Aether as their Traveler, he will befriend Dainsleif and the two become the travelling partners, searching for Lumine, who turned into an evil Princess of the Abyss. On the other hand, if the player chooses to play as Aether, Dainsleif and Aether are former travelling partners, but for some reason, Aether, after becoming the Prince of the Abyss, turns into Dainsleif's sworn enemy.

Bough Keeper: Dainsleif[]

Dainsleif is first introduced in the World Quest "Bough Keeper: Dainsleif", in which he cryptically talks of a travelling partner who he refers to as "her". Together, Aether and Dainsleif learn about Khaenri'ah, a very ancient civilization which is considered cursed: the pure-blooded Khaenri'ah inhabitants have the immortality curse while the impure ones turn into Hilichurls, because they commited much sins and therefore, Celestia decided to make a judgement against them in that way.

We Will Be Reunited[]

Towards the end of the Archon Quest "We Will Be Reunited", Aether and Dainsleif were fighting against the Abyss Emissary, but Aether appears, blocking the attack before they could defeat him. He reveals Dainsleif and Aether that he is the Prince of the Abyss Order. Here, it is revealed that Dainsleif and Lumine do indeed know each other, but they turned into sworn enemies due to the fact that he is the currently working with the Abyss Order, Dainsleif's main opponent. Given from Dainsleif's expressions however, he appears to feel betrayed and hurt by Lumine declaring him as his enemy. Lumine tells Aether that Dainsleif was a royal guard of the final dynasty of Khaenri'ah who failed to prevent its destruction 500 years ago. She also tells Aether that he should not team up with Dainsleif. Aether then tells Lumine to return home with him, but she refuses. Lumine, feeling that fighting with her own brother would be pointless, departs into a portal shortly after that and Dainsleif dashes after her, following her into the portal. But in the end, Dainsleif also lost all Lumine's traces.

Requiem of the Echoing Depths[]

In "Requiem of the Echoing Dephts", Aether finds Dainsleif again, who offers him to travel into the Chasm to show him the Khaenri'ah ruins. They travel together and they soon discover the true nature of the Hilichurls. Due to the reality-changing nature of the curse, Dainsleif deems Lumine's attempt to restore Khaenri'ah to its former glory as a futile effort and tells Aether that it will only bring the hilichurls even more suffering. Aether decides to help him stop his sister's plan, believing that he has no right to subject others to near-guaranteed suffering for an infinitesimally small chance of redemption.

Traveler's Quest Act: Caribert[]

Aether meets Kaeya at a tavern in Port Ormos in Sumeru. During this meeting, Aether picks up information that Kaeya is a descendant of the Alberich family and that this links him to the Abyss. When Dainsleif appears, Kaeya leaves the two alone in their own meeting.

Arriving at a small farming field, Dainsleif finds the area familiar and they investigate. However, some monsters are seen nearby and after defeating them, Dainsleif believes that the problem might be with the Ley Lines. Thus, Dainsleif leaves the camp for the moment and Aether decides to camp there. Dainsleif is trying to wake Aether up, but decides to leave her to rest when he noticed that he was crying in his sleep. According to Chlothar, he kept watch by his side all night.

Traveler's Quest Act: Bedtime Story[]

Aether and Paimon received a commission from Katheryne to find a missing person from Vimara Village. The commission is jointly issued by the residents of Vimara Village and a dozen successive efforts to complete it have all ended in failure. Katheryne informs them that none of the residents know the missing person's name and they can only provide his general appearance. Aether and Paimon accept the commission and head out to Vimara Village. This commission led Aether to meet Dainsleif again. Together, they worked to gain further insight into the Loom of Fate, an operation that Lumine wishes to use to try to destroy Teyvat before Celestia awakens.

Just as Aether and Paimon leave, Lumine appears, wielding her Twilight Sword in an attempt to confront and stab Dainsleif from behind, but the result of their fight is still unknown.

Bough Keeper: Dainsleif[]

Dainsleif is first introduced in the World Quest "Bough Keeper: Dainsleif", in which he cryptically talks of a travelling partner who he refers to as "her".

We Will Be Reunited[]

Towards the end of the Archon Quest "We Will Be Reunited", Lumine appears before Aether and Dainsleif, blocking their attack on an Abyss Herald and revealing himself as the Prince of the Abyss Order. Here, it is officially revealed that Dainsleif and Aether do indeed know each other. Aether however, considers Dainsleif to be his enemy due to the fact that he is the currently working with the Abyss Order, Dainsleif's main opponent. Given from Dainsleif's expressions however, he appears to feel betrayed and hurt by Aether declaring him as his enemy. Aether tells Lumine that Dainsleif was a royal guard of the final dynasty of Khaenri'ah who failed to prevent its destruction 500 years ago. He also tells Lumine that he should not team up with Dainsleif. Lumine then tells Aether to return home with her, but he refuses. Aether then departs into a portal shortly after that and Dainsleif dashes after her, following him into the portal.

Bedtime Story[]

In "Bedtime Story", Lumine and Dainsleif worked to gain further insight into the Loom of Fate, an operation that Aether wishes to use to try to destroy Teyvat before Celestia awakens.

When Lumine and Dainsleif notice that the Abyss Order is still trying to retrieve the Eye of the First Field Tiller first, Dainsleif lures them into a false location and persuades Aether to leave so that he could get Lumine to come out of her hiding place. This works, and as Lumine approaches Dainsleif, he clenches his fist. He tells Aether that he knew going along with his trap would be the only way to meet him face to face. Aether notes that it was a gamble for Dainsleif to risk his safety and that of the eye just to see him, but then also says that he believes he is walking into a trap laid by Dainsleif. Dainsleif is surprised to see that Aether had come by himself, to which Aether tells him that any army he would send would be no match for Dainsleif, so it was better for him to come alone. Aether knows that Dainsleif must have a lot to say, but challenges him to defeat him in a duel if he wants a conversation with him. Dainsleif is hesitant and has a pained expression on his face, but gets ready for the battle anyway.

The specifics and outcome of the duel between Aether and Dainsleif is unknown, but Aether tells Lumine that he didn't expect Dainsleif would be so hesitant to fight him after everything, "Were it not for that... Perhaps I'd still be no match for the Twilight Sword. Even after five hundred years."

Fanon[]

Due to Dainther's obscure place in the Genshin Impact community, it's often overshadowed by pairings such as DainsLumi, Xiaother, Dainkae, and Chilaether. On AO3, it has less than 200 fanfics.
